Tactical Combat Casualty Care (TCCC) is developed by the U.S. Department of Defense, Defense Health Agency (DHA) Joint Trauma System (JTS) to teach evidence-based, life-saving techniques and strategies for providing the best trauma care on the battlefield. NAEMT conducts TCCC courses as specified by the DHA-JTS. NAEMT currently offers three types of TCCC courses.

• TCCC-ASM (TCCC All Service Members – Tier 1) is a 7-hour course for all service members. 
• TCCC-CLS (TCCC Combat Lifesaver – Tier 2) is a 40-hour course for non-medical military personnel deploying in support of combat operations.
• TCCC-CMC (TCCC Combat Medic/Corpsman – Tier 3)* is a 63-hour course for military medical personnel including medics, corpsmen and pararescue personnel deploying in support of combat operations.

The foundational medical science upon which TCCC is based is published in NAEMT’s PHTLS Military textbook in which the military chapters are written by members of the JTS Committee on TCCC. TCCC courses offered by NAEMT are endorsed by the Joint Trauma System and the American College of Surgeons. NAEMT’s TCCC-CMC and TCCC-CLS courses are accredited by CAPCE and recognized by NREMT.

NAEMT's TCCC courses are taught by a global network of experienced, well-trained instructors. To support training centers, instructors and students, NAEMT maintains a network of affiliate faculty both in the U.S. and internationally, and staff at its Headquarters Office.

Tactical Combat Casualty Care (TCCC): In addition to NAEMT’s general instructor requirements, current TCCC instructors and instructor candidates are required to demonstrate knowledge and skills for each of the TCCC tiers they plan to teach (1-All Service Members, 2-Combat Life Saver, 3-Combat Medic and Corpsman), which can be accessed at https://deployedmedicine.com/market/226. Current TCCC-CMC and TCCC-CLS instructors with no military service can maintain their instructor status by teaching the required number of courses each year.
